The oscillations of solutions of boundary value problems for certain impulsive vector neutral parabolic partial differential equations are investigated.By using H-oscillation introduced by Domslak and the method of dimension reduction with inner product,multi-dimensional oscillation problems are reduced to the nonexistence of positive solutions of one-dimensional impulsive neutral differential inequalities.Thereby some sufficient criteria for H-oscillation of all solutions of the boundary value problems are given via first order impuls...
